Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for constructing complex heterocyclic compounds. Commonly employed in cross-coupling reactions such as Suzuki or Buchwald-Hartwig aminations to introduce aromatic or amino groups. Also utilized in agrochemical research for designing novel pesticides and herbicides due to its halogenated pyridine core, which enhances binding affinity and metabolic stability.
